The Real Texas is an action adventure game that plays like a mashup of Zelda: Link to the Past and Ultima VI.
Sam, an ordinary Texas rancher, is on holiday in England when he falls into a blue portal and lands in Strange, Texas. The Real Texas is a pretty even balance between exploration/problem solving, and shooting/dungeons. There are no standard fetch quests or the like but the NPCs in the game all play a part in the unfolding of the story.
